No knowledge of this background is required for players to play the game, but it adds some color to the overall experience. Much of this information is learned in the game by talking to various NPCs.
The story begins in the old world of Orpesia, with the country of Oporuto. Oporuto was starving, and in need of an economic uplift. Their trade with resource-rich Katai had been cut off by the armies of Targa, Illier, and Vespanola to the East, and to the West they were blocked by the dreadful Dark Sea.
